Application February 11, 1936, Serial No. 63,429

This invention relates to a collapsible stove, and it is primarily anobject of the invention to provide a device of this kind which is ofespecial advantage in camping, and the invention further has for anobject the provision of a stove which can be used with equal advantagefor ordinary cooking'purposes, broiling or in preparing food of abarbecue style.

A still further object of the invention is to provide a stoveconstructed in a manner which,

when not in use, may be compacted to occupy a minimum of space tofacilitate either storage or transportation and which can be readilyextended into adjustment without requiring any particular skill.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improvedcollapsible stove whereby certain important advantages are attained andthe device rendered simpler, less expensive and otherwise moreconvenient and advantageous for use, as will be herematter more fullyset forth.

Thenovel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:-

Figure 1 is a transverse vertical sectional view taken through a stoveconstructed in accordance with an embodiment of my invention, certain ofthe parts having a second position indicated by broken lines;

Figure 2 is a sectional view taken substantially on the line 2-2 ofFigure 1 looking in the direction of the arrow, certain of the partsbeing in fragment;

Figure 3 is a horizontal sectional view taken 40 substantially on theline 3-3 of Figure 1 looking in the direction of the arrow;

Figure 4 is a view in perspective of the stove in its folded orcompacted adjustment;

Figure 5 is a fragmentary view in perspective 45 of a portion of one ofthe grate sections as herein comprised.

As disclosed in the accompanying drawings, I denotes a front panel ofthe stove and 2 the rear panel, both being made of sheet metal and Theend portions of these panels I and 2 are hingedly connected, as at 3,with the end panels 4 also of sheet metal and of preferredsize. Thehinge. connections 3 between the panels l, 2, and 4' permit a collapsing55 of the panels as indicated in Figure 4 with the bottom panel 5 andthe front panel I in overlying relation. This adjustment of the bottompanel 5 is permitted asa marginal portion of the bottom panel 5 ishing'edly connected, as at 6, to the lowerma'rginal portion of the frontpanel i, said hinge'co'nnection permitting the bottom panel 5' to bereadily swung into the compacted or folded position as indicatedinFigure 4, or to be adjusted "in the opposite direction to bridge thespace or area defined by the panels I, 2 and 4 when the stoveis'extended for use as illus trated in Figures 1 and 2. V I

The bottom panel 5 is also of sheet metal and is of such dimensions asto have the panels I, 2 and 4 resting thereon from above when thestructure is extended for use. The cornerportions of the bottom panel5are also provided with the openings 1 through which areinserted frombelow the reduced portions 8 provided at the upper ends of the stakes 9.These stakes 9 are of any length desired and are adapted to be driveninto the ground to provide means for supporting the stove structure inworking position. These stakes 9 are of particular advantage in placingthe stove for use upon a hillside as, of course, the required level ofthe stove may be attained by selectively driving the stakes the requireddistances into the ground. These stakes 9 may be of any material whichis believed to best meet the requirements of practice.

The panel I in its central part and closely adjacent to its "lowermargin is provided with a draft opening ID of suitable size while thecentral part of the rear panel 2 in its top portion is provided with aflue opening H. The side marginal portions of the opening I] are definedby the outstanding flanges l2 substantially perpendicular to the panel 2while the upper margin of the opening H is defined by an upwardlyiinclin'ed flange I l. The panel 2 ate. point below the opening ll andsubstantially centralthereof carries an outstanding headed member l5.

' A collapsible chimney C is comprised in my improved stove structureand isadapted when position for communication with the interior of theextended stove structure through the flue opening ll. When applied thechimney G ex tends upwardly and laterally from the rear panel 2 on apredetermined angle of inclination. When thechimney C is applied theflanges l2 of the rear panel 2 are snugly received within the lower endof the chimney while the lower end portion of the top wall, N5 ofthechimney engages over the upwardly and outwardly inclined flange I l.The lower end of the bottom wall ll of the 2; a chimney carries aslotted depending portion l8 which engages over the headedshank l andhas close contact with the rear panel '2. By this means the chimney C iseffectively maintained in applied or working position yet can be readilyremoved as desired.

The panels I and 2 substantially midway their ends have secured to theirinner faces the upstanding lugs l9 and '20 inwardly offset with respecttotheir associated panels I and 2. The

lug IQ of the panel is above'the draft opening 7 l0 and the lug 20 ofthe rear panel 2 is below the flue opening H but their upper endsaresubstantially coplanar.

The end panels 4 have ,hingedly connected thereto, as at 2|, the outerend portions of the grate sections 22 and 23, said sectionssubstantially snugly fitting between the front and rear panels and 2 ofthe stove when the structure is extended for use and said sections alsobeing a of a lengthj'slightl'y in excess of one-half the distancebetween the end panels 4 when in opera-V 'tive position so that the freeendportions of one of the sections,as 23, will lap or overlie the freeend portion of the second grate section 22. The

free end portion of the grate section22 is provided with shortoutstanding lateral extensions 24 terminating in the perpendicularlyrelated lugs 25 whichengage between the lugs l9 and 23 and theassociated panels I and 2 whereby the grate; section 2211ssupported'iniproper position for use, and at the same time the centralpore tions of the front andrear, panels I and. 2 are effectively heldagainst outward separating movement while of'course said front and rearpanels also havetheir central portions held against in mud flex g-a s fThefree end portion of thegrate section 22 is also provided with thetransversely spaced openings or slots 26 which receivethe lugs 21'struck from the outer end portion of the grate section 23. By this meansthe extended grate sections 22 and 23 are held in assembled position andat the same time means are provided for further effectively maintainingthe panels I, 2, and 4 in proper extended or working adjustment.

The upper marginal portion of the front panel I has hingedly connectedthereto, as at 28, a grill 7 plate 29 which is of a length slightly inexcess of the space between the end panels 4 when the stove-is extendedso that when said grill plate 29 panel 2 and in order to permit thepassage of the to. its normal position. the head 32 willbe thrown isswung across the top of the open top of the stove -such plate will beeffectively supported by the end panels 4. The marginal portion of thisgrill fplate 29 opposite its hinge connection 28 is provided in itscentral part'with a slot 30 through which is insertable an upstandinglug 3| andits head 32' carried by the adjacent portion of the rear panel2. The head 32 ofthe lug 3| is disposed at the side of the lug 3| towardthe rear lug 3| and' its head 32 through the opening or slot 30 it isnecessary that the upper central portionof the rearpan'el, 2 beforced'or flexed inwardly, and as such portion of the panel 2 returnsover the adjacent portion of the-grill plate 29 whereby said grill plateis-effectively held, in- Working'position. I H V 1 When the grill platestove is extended, it may be readily swung ,en-

tirely free of the opentop of the stove and .to a position overlying theouter face of the front.

panel ,I as is indicated by broken lines in Figure 1. 7

29 is not in andthe- The upper marginal portion of' the rear panel 2 hashingedly connected therewith, as at 33, a.

marginal portion of a'solid stove top plate 34 of sheet metal and alsoof a lengthslightly greater] than the space between the end panels 4 ofthe extended stove. This plate 34 when disposed over the open top of thestove is usedfor ordinary cooking purposes and while it can be thrownacross the top of the stove with thesgrill plate 29 in its exterioradjustment, said stove top plate 34 may be adjusted over the top of thegrill plate 29 while said grill plate is-still in applied position overthe top of the stove as indicated by broken lines in Figure 1.

When the top plate 34 is not in use it swings entirely to one side ofthe open top of the stove and, as illustratedinFigure 1, is supported inits non-workingposition by contact with the top wall I6 of the appliedchimney C. V

Should it be desired to cook food in a barbecue style, the grill plate28 isthrowninto its position as, indicated by'broken lines ,in Figure .1while the top plate 34 is thrown into its position' as illustrated byfull lines in thesamemfigure, This leaves the top of the stove entirelyopenand the food to be cooked may be placed-upon'a; spit and readilysupported above the fire car ried by the grate sections 22 and 23.Furthermore, in camp shouldit bedesired to have the benefit of the stovepurelyas a camp fire,*the.

plates 29 and 34 will be adjusted in; the same manner just mentionedwhendesired to cook. in barbecue style. a

My improved stove can be nection with different kinds of fuel such aswood, coal, or charcoal, and in -view of, the fore going descriptionitis believed to be apparent that when desired it can be readilycompacted to facilitate transportation or storage.- It is also.

believed to be equally obvious that if desired it can be extended foruse without requiring any particular skill.

From the foregoing description it is thoughttov be obvious that acollapsible stove constructed in accordance withmy invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change and modi-Zfication without departing from the principles and spirit thereof'andfor this reason I do not wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown incarrying. ,outmy inj vention in practice except as hereinafter claimed.
